ro ALL wHoM'lr MAY eoNcERlv;

Be it known that we, DANIEL CATcnroLE, of Geneva, in the county ofOntario, and State of New York, and J. HAVENS, of Auburn, in the countyof Cayuga, and State aforesaid, have invented certain new and usefulimprovements in Wood-Bending Apparatus; 4and'wc do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification, in which- I Figure 1 is a side elevation of oui machine,showing-the attachment for bending carriage-poles.

Figure 2 is a top or plan view of the same, Showing the attachment forbending thills.

Figure 3 is a detached vertical section of the clamping-former forthe'large end of the thills.

Like letters indicate corresponding parts.

The nature of this invention will be better understood by reference tothe drawings and specification, and to enable others to make and use it,we will describe its construction and operation.

We provide a suitable frarne,iA, in the top of whichis hung the shaft Sof the toothed wheel W, which gears into a pinion upon the shaft E. Thisshaft hase. pulley, P, by which it may be driven by power, or it may beturned by hand by a crank, if desired. The axial shaft S is made toproject someinches from the face of the wheel W, from which there arealso two clutch-pins, e. The formers or blocks B are placed upon thesepins, and are forced by them to turn with the wheel. The pinion-end ofthe counter-shaft E is hung in the end ofjthe lever L, which is hingedor has its fulcrum in the brace A. The outer end of this lever rests inthe fork in the top of the standard F, and it is locked'in gear by aclamp in the standard. The primary bed D is hinged in the top of thestandard J, as shown in iig. 1, which is forked at the top, and ismadeabout as wide as the bed. This bed is provided with elevated ribs f,iigs. land 2, between which the sliding bed D moves. The opposite end ofthe bed D is guidedin its vertical movements between two studs, g. Thisend is borne upward by means of the weighted bar b, rock-shaft t, andsupporting bar le. The connectingrod r is hinged to the adjustable clampp, which is attached 'to the hinged bed D by the clamping-screw or boltn, whereby its position may be changed as desired, in order to increaseor diminish the upward stroke of the heade, the bar of which is hingedto the short arm of the lever j. It ispivoted to the hanger x, which isrigidly fixed to the sliding frame. There is a clamping-screw, s, and asliding cross-head, L, attached to the sliding bed D, tig. 1. This bedis grooved to receive the har Z1', the lower end of which is attached tothe bod D by a metallic band or spring, z'.

The' sliding frame D is drawn to the right hand from its presentposition, causing thc connecting-rod r to draw the long arm of the bentlever j up, and the short arm down, and with it the head e. The stick m,which represents a light carriage-pole, is placed through the yoke orcla-mp y, with one end against the lug o', the bar'bei'ng down in thegroove in the bed D. The clamp y is thrown over the end of theformer-block B, where it is secured by the wedge v. The wheel is throwninto gear, and as it turns thc bend is made over the convex face of theformer, and at the same time the bent lever j forces the head e upward,e'ecting that bend in the opposite direction, as shown in iig. 1.A Theclamping-jaw z is then slipped on from'the back side, and secured by thewedge u. The clamping-screw is then reversed, which releases the bar orstick m, and the former B, with the bent stick or pole, is removed fromthe wheel, and another former-block substituted, and the operationrepeated.

The sliding bed D is removed, and the bed D, iig. 3, is substituted, for'bending thills. The bent lever j and its connections are not requiredwith the bed D. There are two cham-faced levers G pivoted to the bed.There is a detachable former, H, placed upon the bed, where it and thetwo sticks a are firmly held by the clamping-buttons n. The former Ff,iig. ,is attached t'o the stock Q by inserting a pin through thev ear q.There is a metallic band or follower, b, attached to the head or stock Qat one end, and to the sliding bed Dl at the other. The foi-mers areprovided with a clutch, c', fig. 3. The rollers R, gs. 1 and 2, are hungto the primary bed, and as the former Q is revolved, producing the bendat the large end of the thills, the sliding bed issdrewn forward,causing the arms of the cams G to swing outward, thus producing thelateral bend at the forward or small endl of the thills. Theclamping-dog d, being previously placed in the recesso in the bed wereD, ho key r is driven through the eyes of the clamp, thereby securingthe thills to this former, und by withdrawing the pin g they may beremoved, after lia-ving placed the clamping-dog g in the position shownin 5g. 2, and turning the buttons nto register t the openings in theformer, and reversing the driving-wheel. The two formers F and H arealso removed with the tliills. The second vertical bend in thecnrringc-polcs may be produced by means of a cam or eccentric upon thelever.

What we claim as our invention', and desire to secure by Letters Patent,is-

1. The arrangement of the sliding bed D', lever j, rod r, presser-heade, former-block i und its clamps, andthe Wheel W, substantially in themanner and for the purposes s'hown :rnd described.

2. The levers G, former H, rotating head Q, and former F, arranged nndoperating substantially in the manner shown and described, for thepurpose of giving the vertical and lateral bends nt the sume time, :isset forth.

3. The arrangement of the levers G, pivoted to the sliding bed D, incombination with the rollers R attached to the bed D, as and for thepurposes specified.
